Big Mek Dreadnutz has been hard at work doing his best to improve WAAGH! Drillteef's mekanoid army. One of the most important things, in his opinion, is to do so while preserving resources. To that end, he has re-used a lot of materials, not the least of which has been the WAAGH!'s legion killa kanz. What has probably been the most notable of these ventures has been Voltrork, Krumpa ov da Ooniverse.
When Big Mek Dreadnutz and his Mekanoid Mob takes the battlefield, the sight of hundreds of tons of clanking destruction is no surprise to most of the WAAGH!'s enemies, but when four Killa Kans and a Deff Dread clang together to form Voltrork, even Drillteef's most formidable enemies quake with terror.
